There's a lot going on during the process of putting on more muscle tissue than just muscle growth.
You have to strengthen your tendons, add in new neural connections (yeah that happens just not in your CNS) to control the muscles, expand and/or
rearrange the tissues around them to make room, add in more vascularization, more lymphatic ducts to dump the leakage, increase the ability of your
liver, lungs and what not to dispose of the waste products etc.
Even the attachments to the bones beef up, you have to lay down more bone around the tendon attachments to keep them from just ripping loose.
